Butterfly mechanism of the MacBook-2015 is only 1mm travel distance; hard to use for any typing, very hard to use for long typing.

This new Magic keyboard is only 1.5mm travel distance, not as hard as the Butterfly, but hard to use as well. Less wobbly than previous Apple scissor switch generation, but you have to understand that the previous generation was a joke and very wobbly.

This and the Butterfly are ok for short texting and short typing. I do not recommend any of these for long typing sessions.
